blocked account because of software update

On tuesday, 17/03/2015, i tried to draw money at the atm - i got 3 slips saying the account was blocked due to technical problems. On wednesday, 18/03/2015 i went into the meyerton branch & they advised it was a software upgrade that had been done & this was why i could not draw money at the atm. They sent a request to unblock the account to the it dept saying it takes a day, maybe 2 days. I tried to draw money today, 20/03/2015, again got a slip advising it was blocked. I went into the vaal mall branch only to be told that they were sure the it dept was still working on the problem. This is unacceptable because if they know there is a software problem, then they should be able to do a batch restore on their system to resolve the problem.
